获取无线网络强制网络门户资讯

问题描述

是否有访问Android的广播，该无线连接是目前一个强制网络门户的方式（需要网络登录）？ Android的，似乎确实有这个内置的。如果没有一个广播接收器，有没有办法来检查圈养门户检查的结果？我相信这是使用这个类，这是从API隐藏的：

Is there a way to access Android's broadcast that the WiFi connection is currently a captive portal (requires web login)? Android seems to do have this built in. If not a broadcast receiver, is there a way to check for the result of the captive portal check? I believe it's using this class, which is hidden from the API:

在4.2之前，它可能使用：

Prior to 4.2, it was probably using:

背景：

我一直用我自己的方法来检测是否无线网络可能需要登录。我会等待一个无线连接的状态，然后ping一个网站，并确保有一个回应。这似乎工作在大多数情况下大。另一种策略是做的Htt prequest并为您重定向或收到回响应体，类似于Android在上面列出的类的策略。

I had been using my own method to detect whether WiFi likely required a login. I would wait for a WiFi connected state, then ping a site and make sure there was a response. This seemed to work great in most cases. Another strategy is to do a HttpRequest and check for a redirect or the response body you receive back, similar to Android's strategy in the classes listed above.

然而，新的棒棒糖是，当无线网络没有连接的移动数据连接使用。这意味着我的平方法仍然会返回结果，并且重新导向不会发生，因为该请求将通过移动数据进行路由。

However, new to Lollipop is that the mobile data connection is used when WiFi does not have connectivity. This means my ping method will still return results, and that a redirect would not happen, as the request would be routed over the mobile data.

有没有办法让Android的电流的WiFi强制网络门户的地位？如果没有，我们可以确保请求越过无线网络，即使没有通过Android作为连接见过？

Is there a way to get Android's current status of a WiFi captive portal? If not, can we make sure a request goes over WiFi even when there's no connectivity as seen by Android?

推荐答案

您不得不使用新的 ConnectivityManager.setProcessDefaultNetwork API强迫你的应用在通信强制网络门户。见的一个例子。

You'd have to use the new ConnectivityManager.setProcessDefaultNetwork API to force your app to communicate over the captive portal. See https://github.com/pawitp/muwifi-autologin/commit/f045fe36f1fd98a106ea652e2d56f7ddfc871760 for an example.

完成code补充说：

final ConnectivityManager cm = (ConnectivityManager) getSystemService(Context.CONNECTIVITY_SERVICE);
                        for (Network net : cm.getAllNetworks()) {
                            if (cm.getNetworkInfo(net).getType() == ConnectivityManager.TYPE_WIFI) {
                                Utils.logDebug(TAG, "Seting process network to " + net);
                                ConnectivityManager.setProcessDefaultNetwork(net);
                            }
                        }
